4 ways to protect against skin cancer (other than sunscreen)
It’s almost May and here in the northeast, front-of-the-pharmacy aisles are filled with myriad brands and types of sunscreen. While sunscreen is essential to lowering your risk for skin cancer, there are other simple, over-the-counter options you can incorporate into your summer skin protection routine.
Nicotinamide may help prevent certain skin cancers
Nicotinamide is a form of vitamin B3 that has been shown to reduce the number of skin cancers. In a randomized controlled trial performed in Australia (published in the New England Journal of Medicine), the risks of basal cell carcinoma and squamous cell carcinoma were si...

Eponymythology: Atraumatic Abdominal Ecchymosis
LITFL • Life in the Fast Lane Medical Blog LITFL • Life in the Fast Lane Medical Blog - Emergency medicine and critical care medical education blog
Overview
We review the original descriptions of 5 eponymous signs (n=6) associated with non-traumatic abdominal ecchymosis.
These commonly cited eponyms involving the abdominal wall and flanks (Grey Turner, Cullen and Stabler); scrotum (Bryant) and upper thigh (Fox) may be useful clues directing the examiner to consider potentially serious causes of abdominal pathology.

Learning to Learn as a Medical Student
By: Alyssa B. Smith, third-year medical student, Chicago Medical School
I began at Chicago Medical School believing the notion that my study methods had gotten me into medical school, so they could therefore get me through medical school. I quickly realized that was a false perception. The volume of material, necessity to retain this material past each exam, and building of knowledge requires stronger learning methods than those I had used in the past, like relying on flashcards to memorize topics.
That’s when I turned to the six study strategies—including spaced practice, interleaving, and elaborate integration—I ha...

Tumor Size (Size of Invasive Carcinoma) in Breast Carcinoma
Breast Carcinoma reporting;Tumor Size (Size of Invasive Carcinoma)The size of an invasive carcinoma is an important prognostic factor. The single greatest dimension of the largest invasive carcinoma is used to determine T classification The best size for AJCC T classification should use information from imaging, gross examination, and microscopic evaluation. Visual determination of size is often unreliable, as carcinomas often blend into adjacent fibrous tissue. The size by palpation of a hard mass correlates better with invasion of tumor cells into stroma with a desmoplastic response. Sizes should...

Featured Neuropathologist: Michael Punsoni, MD
On occasion, we profile a prominent or rising neuropathologist. In the past, we ' ve featured the likes of Craig Horbinski, Roger McLendon,Jan Leestma, and Karra Jones. Today we featureMichael Punsoni, MD, a 2016 graduate of the Brown University Neuropathology Fellowship Program and now on faculty at the University of Nebraska in Omaha. Dr. Punsoni agreed to engage in a little Q&A:1. Why did you decide to become a neuropathologist?I have always had a strong interest in science and medicine, particularly the neurosciences. After college I worked in two research labs, which fueled my interest in basic...

Senolytic Drugs Fail to Kill Cancerous Cells with Senescent Gene Expression Signatures, but a Gene Therapy Succeeds
Some cancerous cells express signatures normally associated with senescent cells, so why not try senolytic compounds against them? This is something of a full circle, given that most of the current senolytic drug candidates were originally characterized and tested as potential chemotherapeutics. The open access paper here is interesting for two points: firstly, that senolytic drugs didn't kill cancerous cells with a senescent signature, and secondly that a suicide gene therapy targeting that signature does work against both normal senescent cells and cancerous cells with a senescent signature. The gene therapy approach rep...

What If The Pathologist Is Wrong?
And they won ' t review all the tests. This is a two part misadventure.First I was horrified by thisfirst story where two women were found to have been misdiagnosed by a pathologist at a hospital in Ireland. Their original breast cancer diagnoses were incorrect. One woman was diagnosed with DCIS in 2010 and had a mastectomy. Based on the original pathology she was not required to have any additional treatment. In 2012, to the surprise of her and her doctor, her cancer came back." Her original 2010 biopsy had shown invasive cancer but this had been missed.The hospital said this was a mistake that any pathologist could have ...

Precision Medicine and Public Health (from Precision Medicine and the Reinvention of Human Disease)
Excerpted fromPrecision Medicine and the Reinvention of Human DiseaseDespite having the most advanced healthcare technology on the planet, life expectancy in the United States is not particularly high. Citizens from most of the European countries and the highly industrialized Asian countries enjoy longer life expectancies than the United States. According to the World Health Organization, the United States ranks 31st among nations, trailing behind Greece, Chile, and Costa Rica, and barely edging out Cuba [42]. Similar rankings are reported by the US Central Intelligence Agency [43]. These findings lead us to infer that acc...
